While configuring Physical standby,We set the parameter Log_Archvie_Dest_2 & Log_archive_dest_State_2=enable in primary.The parameter Log_archive_dest_State_2 enables to send archive log to sepcified location or remote location.Is it right?If it's, why do i need to set Log_Archive_config again?

For your reference , i am sharing the one example from init file . log_archive_dest_1 tells to use the DB_RECOVERY_FILE_DEST as the location to archive to, that it should be used to archive all logfiles in any (all) roles, and that this is for the primary database . The second says that if it is the primary database, it should transport online logfiles using the service name art02 and that the target is the database art02.Regarding third and fourth says that they should be enabled .
